Abstract

A dispenser (10) for flowable materials (34), such as toothpaste, includes a hollow barrel (12) in the form of a tube open at its lower end (18) and closed at its upper end with the flowable material being inserted in the tube. A plunger which is also in the form of a hollow tube having a closed upper end (22), is telescopically arranged in the barrel. A seal is effected by means of a hinged peripheral rim (30) on the outer surface of the piston (20) near its upper end (22). The flow of the material (34) forces the peripheral rim (30) to pivot into sealing contact with the inner surface (28) of the barrel (12). <IMAGE>
